Re: Infected with Trojan Vundo, iifdcAtT.dll, pop-ups, etc.

Hello TheyGotMe. Please tell us how your system is behaving.

Please copy this page to Notepad and Save it to your Desktop in order to assist you when carrying out the following instructions.

Before beginning the fix, read this post completely. If there's anything that you do not understand, kindly ask your questions before proceeding.
Ensure that there aren't any opened browsers when you are carrying out the procedures below.

It is IMPORTANT that you don't miss a step & perform everything in the correct order/sequence.

------------------------------------------------------

Close any open browsers.

Disable your antivirus and antispyware applications, usually via a right-click on the System Tray icon. They may otherwise interfere with ComboFix.

Open Notepad and copy/paste all the text in the codebox below into Notepad:

Collect::
c:\windows\system32\yayaYoPJ.dll
Save this Notepad file as CFScript.txt to your Desktop and then close the file.





Referring to the picture above, drag CFScript onto ComboFix

If you are prompted to update ComboFix, please click Yes

Your desktop may go blank. This is normal. It will return when ComboFix is done. ComboFix may reboot your machine. This is normal.

When finished, it shall produce a log for you. Please post that log, ComboFix.txt in your next reply.

Note:
Do not mouseclick ComboFix's window whilst it's running. That may cause it to stall.


When CF finishes running, the ComboFix log will open along with a message box--do not be alarmed.

With the above script, ComboFix will capture a file to submit for analysis.

Ensure you are connected to the internet and click OK. A browser will open. Simply follow the instructions to copy/paste/send the requested file.


Please let your helper know you successfully submitted the file.
